Find the power rating of the heater, Physics

Assignment Help:

Electrical equipment in an office takes a current of 13A from a 240V supply.

Estimate the cost per week of electricity if the equipment is used for 30 hours every week and 1kWh of energy costs 13.56p

An electric heater consumes 3.6MJ when LINKED to a 250V supply for 40 minutes.

Find the power rating of the heater and the current taken from the supply
